 * This is an abstract layer to insulate the upper usage of tooltip content
 * from the different backends according to different `renderMode` ('html' or 'richText').
 * With the help of the abstract layer, it does not need to consider how to create and
 * assemble html or richText snippets when making tooltip content.
 *
 * @usage
 *
 * ```ts
 * class XxxSeriesModel {
 *     formatTooltip(
 *         dataIndex: number,
 *         multipleSeries: boolean,
 *         dataType: string
 *     ) {
 *         ...

 *             blocks: [
 *                 createTooltipMarkup('nameValue', {
